A glass of a hot water has an initial temperature 80°C, placed in a room where the temperature is 30°C. After one minute the water temperature drops to 70°C. What will be the temperature after 3 minutes? At what time the water cools down to 40°C?
In order to compute the airport reference temperature and the standard temperature with respect to elevation, the monthly mean of average daily temperature and the monthly mean of the maximum daily temperature of the hottest month of the year is found to be 31° C and 42.5° C respectively. The airport reference temperature is:
During the midday 2pm, the temperature of the water that is left out on a table is 18° If the temperature of the surrounding is 34°C and the water’s temperature heated up to 26°C at 2:25pm. After how many minutes will the water’s temperature be 32°C?
